Wall sleeve can now be inserted into the hole.
Insert sleeve from the inside to the outside. The
sleeve should be
approximately 3/16” longer than
the wall thickness.
4. Identify Line Sets
Mark the line sets as necessary to prevent
crossed connections. Crossed line sets will
prevent proper operation.
5. Identify Interconnect cables
Connect interconnect cable and identify cable at
both ends. Cable routed to terminal from rear of
indoor unit.
6. Mounting the Indoor Unit
If right rear exit of line set is used the indoor unit
can now be mounted. Remove retaining clips
from back of unit to allow access to the line set
stubs. Gently form the line set stubs straight
outward. Use caution when forming the line set;
being careful not to kink the copper lines. See
Figure 3.
7. Connecting Line Set
If installer determines the line set should be
connected at this time, see page 13 for torque
standards.
8. Hang the Indoor Units
Once lines are straight, carefully slide the ends of line set out through the wall sleeve. Hook the indoor unit onto
the top clips of the wall plate. Carefully lower the bottom portion of the indoor unit towards the wall,
snapping it
into the clips at the bottom of the unit. See Figure 4.
If using the left rear exit run lines from outside to indoor unit. Form line set to mate to indoor unit stubs and
connect prior to mounting to indoor unit. If necessary run lines along inside wall and carefully remove the
proper cut out from the indoor unit housing. Line sets may be covered with Plastic-Duct for a more professional
job (see page 5).
9. Inspect the Installation
Ensure that the hooks at the top and bottom of the
inside unit are firmly locked in place.
10. Verify the Indoor Unit is Properly Leveled.
Accurate leveling is critical to prevent water damage
during operation.
11. Check the Drain Hose
Observe that the condensate drain pipe does not curve
upward and is in the lower part of the pipe bundle. See
Figure 5.
12. Seal the Hole
Fill the gap between the wall sleeve and the line set
with sealing putty (installer provided) to prevent outside
air and moisture from entering room (see Figure 6).
